Claims.

This invention relates to improvements in packages or containers.

The main objects of this invention are: 7

First, to provide an improved package which is well adapted for use inthe packaging and dispensing of food products such as butter, lard,

oleomargarine and like greasy or oily products, effectively packagingthe contents for delivery and transportation and at the same time onewhich may be readily opened for access to the packaged product.

and bag flaps partially closed and a modified form invention is clearlyillustrated in the accompanying drawings, in which:

of top closure flaps.

Fig. 12 is afragmentary perspective view of a j structure embodying themodified form-of retaining tongues or lugs on the inner containermember, the outer container member being substantially the same as shownin Fig. 11, illustrating another manner of assembling the innercontainer member within the outer container member.

The preferred embodiment of the invention comprises an outer containermember designated generally by the numeral I, an inner container memberdesignated generally by the numeral 2, and a bag or liner member 3 offlexible material arranged within the inner containermemher. This bag 3is preferably oi greaseproof material adapted to receive a predeterminedquan-' tity oi the material to be packaged such as but- Fig. 5 is a topperspective view of the top of g the outer container member with the topclosure flaps partially closed.

The outer container member comprises side walls 4 and end walls 5provided with overlapping bottom and top closure flaps. 'I'hese bottomand top closure flaps are of the overlapping interlocking type,- the topclosure flaps oi the embodiment shown in Figs. 1 to 6 comprising theinner flap 6 having a slit 22 parallel to the edge thereof and a slit 23extending from the slit .22 to the edge. The intermediate flaps 8 arecut away on one edge at 9 to provide an opening through which thedovetail shaped tongue ll may be engaged when the container iscompletely closed as-shown in Fig. 1. dovetailed tongue is engaged inthe slot 22. In the bottom closure of the outer container of theembodiment illustrated, the flap 2| is provided with a recess 1 in theinner edge thereofso that when the flaps 8 are closed upon it; the

tongue III of the flap 24 may be readily inserted and interlocked withthe edges of the inner flaps 8, as shown in Fig. '8. The sideand endwalls are providedwith fracturing lines. 12 disposed in spaced relationto the top end.

The inner container member is adapted to teleinner container member withthe inner container '66 scope within the outer container member and hasThe side and end walls l4 and I5 so that when the inner container memberis telescoped within the outer the tongues serve as retaining lugs ordetents engaging the wall of the outer member as shown in Fig. 6.

The inner container member is provided with non-overlapping opposed topflaps It. The bag is of such length that when it is arranged within thecontainer member it projects a substantial distance above the upperedges of the flaps it when they are in open position. The flaps It maybe folded inwardly upon the opposed sides of the bag which results incollapsing these sides and bringing the opposed edges ll of the bag intoside by side relation, projecting from be- 2,335,918 tongues l3 struckout from the bottom of the such as lard, oleomargarine and-the like, itis desirable for various other uses. I have illustrated and describedembodiments which'I have found tween the fiaps it, see Fig. 4. Thecollapsed projecting portions H are thenfolded down upon tainer memberthrough which the container-is introduced then closed. Care should betaken however that the folded end of the bag and the top closures of theinner container member are at the top end of the outer container member.

When it is desired to have access to the contents the outer containermember may be fractured along the fracturing line I! and the portionthereof above the fracturing lines removed as shown in Fig. 2. Thisremoved portion constitutes acap l9 which may be replaced, the portionof the inner container member projecting above the fracturing line ofthe outer container member constitutinga neck with which the severedpart I 9 may be removably engaged.

very practical, and have not attempted to illustrate other adaptationsas it is believed this disclosure will enable those skilled in the artto embody or adapt my invention ,as may be desired.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent is:

1. In a package, the combination of an outer container member comprisingside walls and overlapping and interlocking bottom and top closureflaps, the sidewalls having alined fracturing zones adjacent to butspaced from the top end thereof, an inner container member comprisingside walls and overlapping and interlocking bottom closure flaps andopposed non-overlapping top closure flaps, said inner container memberbeing adapted to be telescoped within the outer container member andhaving projecting tongues struck out from its side walls adjacent thebottom closure flaps constituting bendable retaining members coactingwith walls of the outer container member for retaining the innercontainer member in telescoped relation therein, and a bag of flexiblematerial inserted in said inner container member with its top end, whenopen pro- .jecting substantially beyond the said inner con tainer membertop closure flaps whereby said top closure flaps may be foldedoppositely upon the sides of the bag to collapse the same inwardly Inthe embodiment shown-in Figs. 11 and 12 the retaining tongues or lugs 26are struck out from the walls adjacent the corners thereof. In thisembodiment the end closure flaps of the outer container comprise theopposed inner members 2i and the interlocking outer members 28 whichhave opposed co-engaging tongues 29. The inner container member is thesame as described with the exception of the forming and position ing ofthe retaining lugs.

Fig. 14 is a blank of the inner container memher, the bottom'closureflaps of which are substantially the same as the top closure flaps ofthe outer container member shown in Fig. 5.

The inner and outer container members may be made of such relativedimensions that-they areeasily telescoped and at the same time, owing tothe retaining tongues of lugs, they are effectively retained intelescoped relation. This is a feature of great advantage in making upthe package. The inner liner or bag 3 can be made of relatively lightmaterial and if desired can be easily sealed when the parts are broughtinto the relation shown in Fig. 4. However, the

tainer has been fractured along the fracturing I lines as shown in Fig.2.

While this container is especially desirable for use in packagingrelatively heavy materials 76 with portions thereof projecting frombetween the edges of the folded top closure flaps and in side by siderelation, the said projecting portions being folded upon one of the topclosure flaps and the collapsed portions projecting at the ends of saidtop closure flaps being folded inwardly over the end edges thereof, theend closure flaps of the outer container being in overlappinginterlocking position over the closed bag, the outer container memberbeing fracturable along said fracturing lines to permit access to thecontents of the packagewithout opening said outer container top closureflaps, the portion of the inner container member projecting above thefracturing zone of said outer container member constituting a neck fordetachably receiving the severed portion of the outer container whichconstitutes a removable cap.
